Pivotable Document Stopper for Controlled Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document receiving apparatuses lack a simple and effective mechanism for controlling the reception of documents into the apparatus main body, leading to inefficiencies and potential damage to documents.
Innovation Solution
A document receiving apparatus with a pivotable document stopper that can switch between a standing posture to suppress document reception and a tilting posture to permit reception, aided by a biasing portion and a control unit to manage the document stopper's position and ensure proper alignment and reception of documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a document stopper mechanism is added to control document reception, then document reception control is improved, but device complexity increases
Solution Approach 1:
The document stopper is designed to pivot between a first posture (suppressing document reception) and a second posture (permitting document reception). This dynamic positioning mechanism allows the stopper to adapt its function based on operational requirements, providing effective document reception control while maintaining relatively simple construction through a single pivoting component rather than multiple fixed mechanisms.
2Reliability
If the document stopper is held in the first posture by a holding portion, then document reception suppression is improved, but ease of operation deteriorates
Solution Approach 1:
The document stopper operates through periodic positioning between two distinct postures. The holding portion maintains the stopper in the first posture during periods when document reception suppression is required, while the control unit periodically transitions the stopper to the second posture when document reception is needed. This periodic action between fixed positions provides reliable suppression while simplifying operation compared to continuous adjustment mechanisms.
Solution Approach 2:
The control unit manages the document stopper's position based on operational conditions. The system incorporates feedback control where the control unit monitors the need for document reception and automatically transitions the stopper between postures, eliminating the need for manual operation and improving ease of use while maintaining reliable document reception suppression when required.
3Reliability
If the biasing portion is added to bias the document stopper toward the second posture, then document reception permission is improved, but device complexity increases
Solution Approach 1:
The biasing portion applies a biasing force to the document stopper, pushing it toward the second posture (permitting document reception). This counteracts any forces that might keep the stopper in the first posture, ensuring reliable document reception permission when the control unit commands the second posture. The biasing mechanism provides consistent directional force, improving reception reliability while adding only a single spring component rather than complex actuation systems.
4Manufacturing precision
If the control unit brings downstream end portions of documents into contact with the document stopper in an intermediate posture, then document alignment is improved, but ease of operation deteriorates
Solution Approach 1:
The control unit transitions the document stopper to an intermediate posture between the first and second postures before document feeding begins. In this intermediate position, the downstream end portions of stacked documents are brought into contact with the document stopper, which preliminarily aligns the documents in the stacking direction. This preliminary alignment action ensures proper document positioning before the stopper transitions to the second posture for normal reception, improving alignment precision while the control unit automatically manages the transition sequence.

AI summary
A document receiving apparatus comprises a receiving port configured to receive a document into an apparatus main body, a document stopper configured to be pivotable between a first posture in which reception of the document is suppressed and a second posture in which the reception is permitted, a holding portion configured to hold the document stopper in the first posture, and a biasing portion configured to bias the document stopper held in the first posture to be set in the second posture
